This device is necessary for connecting a SEGA dreamcast to a computer's modem via phone line. This is so that the dreamcast can get access to the internet. This is used in popular projects such as DreamPi.

It provides power to a dry telephone line allowing phones and modems to be used without a telephone network. This is popularly used with a SEGA Dreamcast to get online, but it can also be useful for connecting two computer modems together or even just two telephones.

In particular this is handy for computers with software modems. Any modem that needs drivers is a software modem. They do not produce their own line voltage. Two soft modems can communicate with each other using this device.

The Call Attendant (callattendant) is an auto attendant with an integrated call blocker and voice messaging system running on a Raspberry Pi. It stops annoying robocalls and spammers from interrupting your life. Let the Call Attendant intercept and block robocallers and telemarketers before the first ring on your landline.

The callattendant provides international support with configurable phone number formats, with flexible and editable blocked-number and permitted-number lists.

Works with a US Robotics 5637 USB modem, not VoIP.

The Phone of the Wind originated in Japan by its creator Itaru Sasaki, while grieving his cousin who died of Cancer. He purchased an old-fashioned phone booth and set it up in his garden. He installed an obsolete rotary phone not connected to wires or any "earthly system." Here, Itaru felt a continued connection to his cousin and found comfort and healing amid his grief. Itaru gave his phone booth a name, Kaze No Denwa (風の電話), translated as The Telephone of the Wind.

The Phone of the Wind is a shrine mindfully created to connect people to their loved ones on the other side. It is one of the world's most powerful resilience sites. Grievers travel from around the world to "call" their loved ones in spirit, to say the things they didn't get a chance to say while the person was living. It is a place that offers the peace and solitude grievers need to work through their pain. Itaru Sasaki has inspired the creation of many beautiful spaces all over the world with the sole purpose of holding space for a griever. One where the wind will carry their words to those they love who have gone ahead.

We’re an amateur phone collective in Philadelphia! Are you a hacker, artist, or engineer? We need your help!

PhilTel is looking to install new (to us) payphones within the city of Philadelphia. Any payphone installed will be completely free-to-use, allowing the user to place calls within North America. Additionally, we would like to provide various experiences and services through the phones; these could be as simple as voicemail, fun as a phone number that randomly calls other payphones, or as complex as an integration with phone collectors’ networks to allow phone-phreaking and exploration!

A still alive and updated archive of telephony information. Area codes, exchanges, regional telcos, rate centers, deployed hardware types, and more.

You can even search on some data sets.

The Telephone Central Office Building Pictures website was created for one reason only - historical preservation.

The telephone central office is the location where local landline telephone switching takes place. Inside is a specialized electronic telephone "switch" where phone calls are transferred from one customer to another, or to another central office via a long distance circuit.

The central office is almost as old as the telephone itself. Often times these buildings were built many years ago with an architecture that has been long ago forgotten. Many times these buildings were very large to accommodate the analog switching equipment of the day - Step by Step, Crossbar, Panel or early electronic. These days almost all central offices have modernized their switching equipment to a fully electronic system that takes up only a tiny space where years ago large electro-mechanical systems took up floors of space.

As telephony has changed over time, many people are now abandoning the traditional landline telephone for cellular or various Voice over IP methods. The theory is that as traditional landline use goes down, these buildings of yesteryear may disappear.

The goal of this website is to preserve these buildings for future generations in the years ahead. About 50 years ago, a telephone preservationist called "Mark Bernay" started recording telephone sounds. He now has a website called Phone Trips. Also on that website are sounds from his friend "Evan Doorbell" from 45 years ago. All the switching equipment that made these sounds are long gone. With the help of these two folks and others like them, we are able to listen to these sounds today. This site has as similar goal - preserving what we have now for people to look at in the future.

A utility to automate the installation, maintenance, and debugging of Asterisk/DAHDI, while integrating additional patches to provide the richest telephony experience. Useful for: Automating installation and maintenance of Asterisk, Asterisk Test Suite, Asterisk Test Framework, DAHDI Linux, DAHDI Tools, and related resources; validating Asterisk configuration; finding common syntax errors in dialplan code; finding missing audio files referenced by the Playback, BackGround, and Read applications; suggesting optimizations that can be made to dialplan code to make it more readable and efficient; generating Asterisk user documentation; debugging Asterisk configuration; generating core dumps, automating PhreakNet boilerplate dialplan installation.

Primarily supported on Debian-based Linux systems. Support has also been added for FreeBSD. Pull requests to add support for other Linux distros or BSD are welcome.

A collection of useful information and tools pertaining to DTMF.

A simple v.23 modem including the data link layer. This is an application for Asterisk. Place a call over SIP and it'll connect via Telnet to a pre-configured service in the dialplan.

This is F.O.B. (Flexible Orange Box), inspired by the popular S.O.B. (Software Orange Box) program for Windows.

When connecting SIP FXS devices with a Class 5 switch, the ATA will not see a Call Waiting presented to it when there is a Call Waiting. Thus, it is necessary to signal the FSK directly to the CPE in-band from the switch. Asterisk does not have any provision to do this, so this needs to be done with an external program.

This program is intended to be a legitimate Type II Caller ID Generator, used for the purpose of Call Waiting Caller ID (Of course, functionally, it can be used just like any other orange box to spoof call waitings if desired - we are not responsible for any misuse of this program). This allows you to send Call Waiting Caller ID to a remote endpoint, even if no Call Waiting is presented to the remote endpoint (e.g. Analog Telephone Adapter), allowing for CWCID to be provided even when advanced bridging capabilites are being used, by "orange boxing" in band for legitimate purposes.

A self-hosted app utilizing Twilio to manage and direct calls from the enterphone to each of our phones. As an added bonus, it also trigger Philips Hue lights in our apartment to flash when a buzz is incoming. When a visitor dials your unit on the enterphone, the call will go out to the Twilio service, and will connect to the app running on your server. When the app receives a valid request originating from the Apartment Enterphone number, it will drop that call into a conference room (with hold music) while it then initiates calls out to the two tenants.

When a call one tenant is answered, the call to the other tenant is terminated, and the answered call gets dropped into the same conference room, beginning the conference. You can then speak to the visitor, and key presses get passed through to the enterphone system for remote unlocking of the door.

dialup.world is (currently) a three-line dial-up ISP!
